CAR-DOOR.

Specification of Letters Patent.

Patented Feb.. 5, little.

Application filed April 3. 1915. Serial No. 19,030.

To all ceo/m. 'it may concern.'

Be it known that l, FRANK J. Gunner, a citizen ot the United States, residing at Butfalo,`in the county ot llrie and State ot New York, have invenrd certain new and useful Improvements in Car-Doors, of which the following is a specification, ret erence being had therein to the accompanying drawing. i

The object ot this invention to provide metallic devices to replace the internal boarding commonly7 en'iployed in cars to be loaded with grain, and with this object in view l provide a vertically divided two-part closure ot' which one part may slide ho 1izontally past the other` to open the side ot the doorway, while both parts may swing together, from closing position, on a horizontal axis above the lower edge ot the closure.

ln the accompanying drawings,

Figure l is a side elevation of a portion of a car provided with my devices.

Fig. 2 is an enlarged section o'n the line 2 2, Fig. l, parts being broken away, and the doorway being tally closed.

Fig. 3 is a vertical section at the doorway showing the closing plates when materially oiferlapped by the opening of Vone ot them.

Fig. 41 is an axial section ot the middle portion oit' one of the plate-supporting bars which engage the door posts.

Fig. 5 is a section at 5--5, Fig. -1 looking toward the left.

Fig. 6 is a view looking trom the right in Figs. 1, 2, parts being broken away to show the end of the post-engaging rod and its end bearing.

In these views, A represents the side ot a freight car, and B, B two overlapping metal plates sliding horizontally one upon the other to open and close the lower' part ot the doorway. the plates extending above the line for loads of loose granular material. Each plate has its four margins stiened by one or more commercial angle irons fixed to the plate and to cach other where two are used. As shown, each plate has hired to that margin .next the door post C an angle iron D, and to its opposite margin two angle irons E, F riveted togetherto form oppo sitely turned hooks which engage as in Fig. 2 when the doorway is fully closed. The plate B has at top and bottom similar anH gle irons E, F", which form hooks to engage the upper and lower margins ot `the top, bottom, and middle ot the structure.`

Each rod involves a two part tube l-l having its parts connected by a turnbuckle l and slidable in bearings J, K carried by the platel B, and further of a second smaller tube or rod telescoping in the tube H and sliding in a bearing M' fixed to the distant margin oi:l the plate B. At the bearing il. a, plug N is fixed in the end of the tube lil and provided with a non-circular flange l sliding without rotation in a way P ,in the bearing and having a tapered end to enter an aperture in the door post, which is preferably provided with a bushing t). To the opposite end ot the tube H is tixed a non-circular sleeve K which slides in a corresponding way in the bearing K and diminished in size near one end to receive and guide the tube L which is at will locked therein, when the rod is fully extended, by suitable means, for example, a cotter pin. rlhe bearing M at the opposite end of the tube L and coasting parts are similar in every way to the corren sponding parts at the bearing J.

ln use, the rods beingwithin the lateral margins ot the plates, the plates are placed in the doorway as in Fig. l, and by operating the turnlnickles the ends of each are prin jected into engagement with the door posts, as indicated in Figs. l and 2. Strips R are then tiXed to the car tloor to close crevices at the lower edges of the plates, and the car is ready for loading.

When it is to be unloaded, the turnbuckles serve to withdraw each end of the rods, since no part ot the latter can rotate. Usually, the lower and middle rods only are thus retracted, the cleats R are removed, and the closure swings on the upper rod allowing discharge across the whole width ot the doorway. When the closure is not to be used the two plates are moved on each other narrowing the structure to practically halt its extended width, in which torni it is far more easily handled, one man being able to move it to any position. within or without the ear, without di'tticulty.

llVhat l claim is:

l. The combination with a grain carrying car having suitable holes in its door posts, of a closure for the lower part of the door opening, consisting of two laterally overlapping sliding door sections adapted to interlock marginally when extended to fit between the posts, telescoping rods mounted on'the exterior of the sections and extending across the doorway to enter said holes when extending` beyond the door margins, and means for forcibly projecting the rods into v said holes.

2.V The combination with a car door consisting of two horizontally sliding sections overlapped at their vertical sides and adapted to interlock when extended to fill the space between the car door posts, of a series of horizontal rods, each consisting of two telescoping sections, mounted upon the outer faces of the door sections to slide one within the other when one of said sections slides with respect to its companion, means for forcibly sliding the rod sections in either direction to control their engagement with the door posts, and means for positively locking the rods in post engaging position.

3. The combination with a car door consisting of two horizontally sliding laterally o\ierlapping sections adapted for marginal interlocking when fully extended, of a series of horizontal rods each consisting of two telescoping sections extending from side to side of the door, one of the sections being rmounted to slide in bearings near the margins of one of the door sections and the second telescoping with the one and sliding in a bearing at the other margin of its door section, means for forcibly extending each rod, and means for locking together the sections of each when extended.

t. The combination with a car provided with suitable rod-receiving holes in its door posts, of a door consisting of two overlapped horizontally sliding door sections adapted to interlock marginally when extended and to swing in a vertical plane while fitting between the door posts, horizontal rods mounted upon the sections and extending across the door near the top and bottom ot the same respectively and each consisting of two telescoping sections mounted to slide in bearings upon the door sections, means for projecting the rod sections oppositely into the corresponding holes in the door posts, and means for locking the extended rod sections against retraction; the engagement of the upper rod with the door posts being pivotal.

The combination with a grain carrying car having suitable rod-receiving holes in its door posts, of a closure consisting of two laterallv overlapping sliding door sections normally fitting between the door posts, telescoping rods mounted on the sections and extending from side to side of the door, means for sliding the rod sections oppositely into and out of engagement in the corrosponding holes in the door posts, and external strips secured to the car Hoor along the outer faces of the door sections.

G. The combination with two horizontally sliding door sections each of thin metal hav ing its margins stiffened by angle iron and adapted to interlock its companion when the two extend from side to side of a` doorway, of a series of hollow, horizontal, extensible rods each slidably held in bearings upon one of the door sections, a corresponding series of rods sliding in bearings upon the other door section and always telescoping the hollow rods, respectively, and means for rigidlv connecting the telescoping rods.

In testimony whereof I aiiix my signature in presence of two witnesses.
